Rodman Guns

The Rodman Guns are, for all practical purposes, the successors to the columbiad, and for all practical purposes columbiads themselves. Thomas J. Rodman devised the system to produce these guns just before the war. Foundries used a hollow-core, water-cooled when casting these guns. They ranged in size from 8-inch to 20-inch calibers. Although they served to the eve of the 20th century, these guns scarcely fired a shot in anger.
